    Hello,

    The RadUploader seems to work slower than expected. What are the parameters / settings to look for, to manipulate this file transfer speed? (Of course already considering bandwidth disk speed and CPU of the server)

    Kind regards,
    Jeroen

    Hello Jeroen,

    The speed of the RadUpload control depends on the buffer size as each file is separated in chunks, which get send one by one to the server. The buffer determines the size of the chunks and is measured in bytes. You can control the buffer size either through the RadUpload.BufferSize property or through the maxRequestLength settings applied in the web.config file. You can find more info about both properties here. Controlling these settings will allow you to control the speed of the upload.

    I experimented with the RadUpload.BufferSize and maxRequestLength  but my speeds still dont exceed 30KB/sec.
    If i use ftp client to upload a 3MB file it takes 4 seconds, waiting a minute and a half with radupload is too much for my end users.

     Are there any other things i can try? 

    Regards,
    Jeroen

    Hello Jeroen,

    I am not sure what might be causing such an issue. If there are no bugger constrains on the upload, it shouldn't slow down the uploading process at all. For example on our side a 4MB file is being uploaded for less than a second. This is why I wanted to ask you to try this demo solution and let us know if the uploading process with it is still slow.

    Hi Tina,

    I had tried increasing the buffersize before, but apparently not by a large enough amount. I now have it set at 1024000, and that fixed the problem. Could this have any unwanted side-effects though?
